Ok, I've got a 1990 Honda Civic DX 4 Door 1.5L NO modifications what so ever.

All in the area where my heater/ac panel, stereo, cigarette lighter area is, has stopped working. However it works if I have the key in the auxiliary position. It started out as me having my radio on (re-wired to make sure its not grounding out or anything like that) and when I go to switch on the heat, everything in that panel would shut off (ac/heater, stereo, cigarette lighter). It used to come back on after awhile of driving but hasn't come back on since (unless the key is in auxiliary). Any help anyone can provide me with will be greatly appreciated. Also, if you have any questions for me, PLEASE ask me. Thanks in advance everyone.

 

It's a keyswitch problem most likely, all those accessories run off of ignition switched power, so I'm guessing one of your sets of switch contacts is dirty or failing. The fact that it works with the key in aux is the big tipoff.. This means that everything is getting power like it's supposed to, but where the power comes from is faulty.
